Great-sounding compression - without the noise

The Keeley 4 Knob Compressor makes your guitar sound great, without introducing noise into the signal. You also get the controls to shape your sound exactly the way you want it. The 4 Knob Compressor is a pedal you'll never want to be caught without. Whether onstage or in the studio, you'll come to rely on the Keeley 4 Knob Compressor as an essential component of your guitar sound.

Weapons-grade build quality

Keeley's 4 Knob Compressor may be small, but it's packed with ultra-high-grade components. Guitar pedal guru Robert Keeley wouldn't have it any other way. You see, Robert knows that metal film resistors and capacitors translate into ultra-clean operaton. In his quest for the absolute sound, he even hand matches transistors to less than one percent tolerance. With its weapons-grade build quality, you can also rest assured that your Keeley 4 Knob Compressor will stand up to road abuse and give you many years of great sound and trouble-free operation.

Four knobs = iron-fisted control

The Keeley 4 Knob Compressor gives you iron-fisted control over you guitar sound. The Sustain knob lets you dial in the exact amount of compression you want. The Level knob is your output control. With minimal sustain and lots of level, you essentially have a clean boost. The "4 Knob" is a deluxe model featuring two additional knobs not found on the standard (and otherwise identical) Keeley Compressor. Attack lets you shape the front of your notes - the ictus. Turning this clockwise will preserve and emphasize your pick attack by starting to squeeze the signal later. Combining different settings of the 4 Knob's controls gives you a near-infinite amount of dynamics control over your guitar sound.
